Abstract: Based on Mengcun mine, the main shaft equipment , such as the shaft guide, bunton, attended model and anticorrosion method, are detailed in this paper. Since buntons used in large ship are often long-spaned and heavily loaded, the deflection is usually excessive. In order to solve this problem, it is proposed to support the bunton by a beam. The beam structure feature and strength calculation are also given. These measures make the equipment safer and more reliable.
